well yes the white with red eyes is a definite albino (if it looks like this...)
http://www.google.co.uk/imgres?imgurl=ht…(the white one).
i can tell you that none of those are roborovskis - i know cus i've just spent the last 5 months of my life researching them cus i'm getting them for christmas. besides robos are like a browny grey colour and white usually.
no thy're not typical robo colour anyway, robos are browngrey and sometimes they come in a rare white colour. so no not robo.
pet shops do notcare and will not care what type the hamster is so long as it has sold. so dont rely on them.
if your dark grey looks like this then its a campbell:
http://www.google.co.uk/imgres?imgurl=ht…or something like that...
the only other main type i can think of is the chinese dwarf - although its not dark grey but it does have like a stripe running down the back...
http://www.google.co.uk/imgres?imgurl=ht…cus its not a syrian cus syrians dont have stripes down their back.
maybe - maybe it IS a robo - but a very special robo. if the pet shop is right. cus then all hamsters are different - some very different. without pictures i cant really say much...
anyway goodluck! isuggest looking up bout every single typeof hamster on the internet lol XD goodluck!
basically robos ar incredibly small and extremely fast. the other dwarfs are still small, not as fast. robos love to run. the others like to climb and dig more.
finally all hamsters havve different personalitys. like they usually say that girl hamsters are more active than boys. WELL my boy was more active than my girl so what can they say!!?? so yeah their behaviour is similar anyway. hamsters are hamsters lol. they all like to run dig do whatever :)
